HINGE-JOINT FOE, WIND-SHIELDS;

Patented Nov. 23, 1915.

Application filed September 12, 1912-, Serial No. 783,435. RenewedSeptember 22, 1915. Serial No. 52,104.

To (ZZZ whom it may concern:

Be it known that L Pnrnn N. LANDINE, a citizen of the United States,residing at Miliord, New Haven county, State of Uonnecti- 4t and 5 aredetail views.

1 represents one corner of the frame of the transparent section of thewind shield.

2 represents a supporting arm.

The parts 1 and 2 are adjustably hinged together.

3 is a pivot block of unique construction having a split hub forming anexpansible plug and comprising two parts 4d revolubly mounted within ahead 5 on the support 2. The hub or plug parts 4 4c are preferably anintegral part of the block 3 and are separated by an undercut transversechannel or slot in which is located a wedge 6.

7 is a thumb bolt which screws into the wedge 6, said thumb bolt havinga shouldered portion 7 which rests against the outer side wall of thehead 5 so that as the thumb bolt is tightened up, it will draw the wedge6 outwardly, tending to expand the members 4ld forcing them into bindingengagement with the surrounding wall of the head 5. thus locking theframe 1 at any desired angle relatively to the support 2.

In the preferred construction, the block 3 is provided with a shoulderedoffset 8, and the periphery of the shouldered ofl'set is provided withan annular groove 9 which is covered by a flanged portion 10 of the head5. A retaining pin or screw 11 carried by the flange 10 may project intothe groove 9 to hold the parts against accidental separation in theevent the thumb bolt 7 is entirely removed.

By this exceedingly simple form of construction, which is capable ofbeing manufactured at a comparatively small cost, an effective windshield joint may be produced which possesses the maximum durability.

It will be observed that not only does the action of the thumb screw andwedge tend to expand the two parts of the hub block, but they also drawthe hub block laterally into endwise binding engagement with the head sothat theentire area of contact be tween two adjustable part-s serves tofrictionally hold said parts against accidental displacement.

What I claim is:

1. An adjustable hinge joint for wind shields comprising two relativelymovable parts, one of said parts comprising a head having a cylindricalcavity in one face thereof, the other of said parts comprising a hubmember including a clamping block transversely slottedand undercut andarranged to seat within the head cavity and to engage the inclosingwalls of said head, a clamping member seated in the transverselyextending undercut slot in said clamping block between the transverselyseparated portions thereof and thereby held against rotation in saidblock, and an operating member carried by the end wall of the head andconnected with the clamping member to draw the same laterally towardsaid end wall, whereby to bring the transversely separated portions ofthe clamping block into frictional clamping engagement with the walls ofthe head cavity.

An adjustable hinge joint for wind shields comprising two relativelymovable Darts. one of said parts comprising a head having a. cylindricalcavity in one face thereof. the other of said parts comprising a hubmember including a clamping block.

said block being transversely slotted and having its slotted edgesundercut, said block being arranged to seat within said head cavitv andto engage the adiacent walls of said head, a wedqe arranged between thetwo undercut sections of said block and formed toenaaae with theundercut edges thereof. an operating device passing through the end wallof said head and screwing into said wedge and having a bearing againstsaid head whereby said wedge may be oper Eated to expand said block intofrictional clamping engagement with the walls of said head cavity, andmeans independent of said operating device for holding said relativelymovable parts against accidental separation.

3. An adjustable hinge joint for Wind shields embodying two relativelymovable parts, one of sald parts BOHlDllSlIlg a head having acylindrical cavity in one side thereof, the'other of said partscomprising a'hub member, a block carried thereby, said block beingtransversely divided and undercut and arranged to seat within said headcavity, and engage the adjacent walls thereof, a wedge arraneed betweenthetwo undercut-sections of the hub block, an operating device passingthrough the end Wall of the head and screwing, into said wedge, andmeans for holding the parts against accidental'separation independentofthe thumb screw, said means comprising a groove in ,the periphery of theinterior part and a projection on the exterior part extending into saidgroove.

4:. An'adjustable hinge joint for wind shields and the like comprisinga. head havinp, a cylindrical cavity in one side thereof, a frame, a hubblock carried thereby, said hub block being transversely divided andundercut and arranged to take a bearing in said head, a wedge arrangedbetween the two. undercut sections of the hub block, an operating devicepassing through the end wall of the head and screwing into said wedgeblock, and means for holding the parts against accidental separationindependent of the thumb screw.

5. An adjustable hinge joint for wind shields and the like comprising ahead having a cylindrical cavity in one side thereof,

shields and the like comprising a head havinn a cylindrical cavity inone side thereof, a frame, a hub block carried thereb said hub blockbeing;- transversely divided and undercut to form two integrallyconnected hub bearing pieces arranged to take a beari119, in said head,a wedge arranged between the two undercut sections of said hub block, anoperating device for moving said weda'e against said undercut sectionsto expand the same and force them into combining contact with said head.
